Reika always maintained a sweet and affectionate demeanor toward her son, Takahiro, who in turn found himself deeply drawn to her kindness. One day, Reika discovered that Takahiro was masturbating using her underwear. Though she pretended not to notice his flustered reaction, inside she was deeply stirred. That night, Takahiro nervously approached his mother and whispered, "Mom... will you make me a man?" Hesitant at first, Reika slowly reached out and began to fulfill his request orally. But unsatisfied with just that, she softly murmured, "Poor little virgin baby, let Mommy teach you everything," guiding him gently through cunnilingus, handjob, missionary, doggystyle, and finally giving him a creampie, enveloping him in tender incestuous pleasure.
